Welcome to another essential episode of the FlightBridgeED Podcast: MDCAST, where we dive deep into the complexities of critical care and continue our high-risk OB transport conversation. This episode focuses on the often overlooked yet rapidly increasing crisis of hypertensive disorders in pregnancy. Host Dr. Mike Lauria and maternal-fetal medicine specialist Dr. Elizabeth Garchar discuss the full spectrum of hypertensive disorders—from gestational hypertension to the life-threatening condition of eclampsia—and share practical insights on managing these critical patients in prehospital and transport settings.
Starting with foundational definitions of specific disorders like pre-eclampsia vs. eclampsia and HELLP syndrome, they explore the physiological mechanisms driving preeclampsia, the increased mortality rates, and why transport providers are seeing more cases in rural or under-resourced facilities. Learn how to distinguish between different diagnoses, manage acute cases in transit, and navigate treatment protocols with a detailed look at magnesium sulfate's role and the right blood pressure control strategies. This episode brings expert-level insight to providers of all backgrounds, from the basics to the most advanced interventions.

Key Takeaways:
- Pathophysiology of Preeclampsia: This condition often arises from placental abnormalities that lead to widespread vascular issues, impacting both the mother and fetus.
- Magnesium Sulfate in Management: Magnesium sulfate is vital for preventing eclampsia and should be monitored for toxicity, especially in patients with reduced kidney function.
- Identification of Hypertensive Disorders: A blood pressure reading of 160/110 mmHg or greater post-20 weeks' gestation is a significant indicator of hypertensive disorders, warranting immediate medical attention.

Cardiac Cowboys
The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
